3 Claims.

This invention relates to a cutting instrument and it is primarily an object of the invention to provide a device of this kind especially designedand adapted for use in cutting puppies tails.

It is also an object of the invention to pro vide a device of this kind whereby the instrument can be readily and effectively engaged with the tail of the animal and wherein the severing means of the instrument is mounted for selective adjustment so that the cutting operation may be effected at a selected distance from the base of the tail.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved cutting instrument whereby certain important advantages are attained, as will be hereinafter more fully set forth.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawing, wherein:

Figure 1 is a view in top plan of a cutting instrument constructed in accordance with an embodiment of the invention;

Figure 2 is a view in side elevation;

Figure 3 is a fragmentary sectional view taken substantially on the line 3-3 of Figure 1;

Figure 4 is a sectional view taken substantially on the line 44 of Figure 1; and

Figure 5 is a view in front elevation with a portion of the applied grommet broken away.

As disclosed in the accompanying drawing, the instrument comprises two elongated fiat arms I possessing a certain degree of inherent resiliency and which have adjacent ends connected by an intermediate plate 2. The arms I and plate 2 are preferably formed from a single blank of material.

The extremities of the arms I remote from the intermediate portion 2 are free and said extremities carry the plates 3 substantially at right angles to the arms I and which are provided in the opposed marginal portions with the substantially semicircular recesses 4 so that when the arms I are forced toward each other, as by the grasping of a hand, a rubber grommet 5 will be effectively held between the plates 3 or jaws as they may be called.

The grommet 5 is provided circumferentially therearound in its periphery with a groove or channel 6 in which are received the rounded marginal portions or the plates or jaws 3 to assure the effective maintenance of the grommet 5 in applied or working position.

The grommet 5 in its center is provided with an opening I of a predetermined diameter wherea by the grommet may have inserted therethrough the puppy tail to be out. In practice, there are to be a number of the grommets 5, the opening 6 of each differing from that of the others, so that there will be grommets having difierent openings as may be required by the tail diameter variations.

One of the arms I is provided therealong with an elongated slot 8 through which is directed the shank 9 of a conventional headed member and which shank 9 is carried at a fixed point by a slide plate I0 overlying the inner face of said slotted arm.

Coacting with this shank 9 is a wingednut II or the like whereby the slide plate It may be locked in selected adjusted position along the arm I and as may be determined by the linear graduations I2 carried by the plate Ill and which, as herein disclosed, extend from the. outer end of the slotted arm I to a desired distance inwardly thereof as, for example, four inches.

The forward end of the slide plate I0 carries the inwardly disposed plate I4 substantially at right angles to the plate Ill and which is provided in a marginal portion with a recess or notch I5 having a knife edge, whereby the plate I4 constitutes what may be termed the stationary blade of the cutting means.

Pivotally connected with the inner end portion of the plate or blade I4 is a swinging plate or blade I6 provided in its inner margin with the recess ll having a knife edge and which knife edge coacts with the knife edge of the notch I5 of the plate or blade I4 when the plate or blade I6 is swung inwardly of the plate or blade l4. The plate or blade I6 is also provided withan extended handle member I8 to facilitate the desired cutting movement.

It is believed to be readily apparent that in practice the slide plate II) will be adjusted lengthwise of the slot 8 to a point determined by the aduations I2 in accordance with the desired length of tail stump desired. It is also believed to be readily apparent that the instrument is one which can be readily applied to the tail of the animal and can be effectively and conveniently operated to obtain the desired severance of a tail.

From the foregoing description it is thought to be obvious that a cutting instrument constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated.

What is claimed is:

1. An instrument for severing puppies tails comprising two elongated arms movable one toward the other, a grommet through which the tail to be severed is adapted to be threaded, means carried by the arms for releasably holding the grommet between the arms, and a cutting means carried by one of the arms and positioned between the arms.

2. An instrument for severing puppies tails comprising two elongated arms movable one tothe grommet between the arms, a cutting means carried by one of the arms and positioned between the arms, and means for selectively adjusting the cutting means lengthwise of the arms.

3. An instrument for severing puppies tails comprising two elongated arms movable one toward the other, a grommet through which the tail to be severed is adapted to be threaded, means carried by the arms for releasably holding the grommet. between the arms, and a cutting means carried by one of the arms and positioned between the arms, ,said cutting means comprising a stationary blade and a movable blade carried by the stationary blade.
